A Risk Control Matrix Maps Adolescent Bullying Risks and Prevention Priorities in Indonesian Junior High Schools

In the complex ecosystem of a school, the social dynamics between teenagers can sometimes turn toxic. This phenomenon, known as bullying, is not merely a rite of passage but a serious threat to a student's physical safety and mental well-being. It manifests in various forms, ranging from direct physical harm to subtle verbal intimidation and the exclusion of peers. While schools often have rules against such behavior, understanding exactly how these incidents occur, who is most vulnerable, and what specific actions cause the most harm is essential for creating effective safety measures. Researchers have long sought to move beyond simple reporting of incidents to a more structured approach, one that maps out risks like a safety engineer would map a building's hazards, identifying which dangers are most severe and which prevention strategies will work best.

A team of researchers from Jenderal Soedirman University in Indonesia set out to apply this kind of structured risk assessment to the reality of junior high schools in the Banyumas Regency. They focused on a specific question: what are the most common types of bullying happening in these schools, and what factors make a student more likely to become a victim or a perpetrator? To answer this, they surveyed students across five public junior high schools in the Purwokerto Timur District. The study involved asking students about their experiences with bullying, their use of digital devices, their gender, and whether they had previously experienced violence. The researchers then organized this data into a "Risk Control Matrix," a tool that sorts bullying behaviors by how often they occur among perpetrators and how dangerous they are, allowing school administrators to prioritize their responses based on the severity of the threat rather than just reacting to individual complaints.

The results of the survey revealed a landscape of aggression that was both widespread and varied in its intensity. The most frequent and dangerous form of bullying identified was physical hitting, which the study found to be a risk factor for 35.19% of the perpetrators surveyed. The researchers classified this as an "Extreme Risk" because of its high prevalence among those who commit bullying and the potential for long-term trauma. Following this, verbal threats were the next most significant issue, identified as a risk factor for 14.81% of the perpetrators and categorized as a "High Risk." While less physically damaging than hitting, these threats create an atmosphere of fear that disrupts the learning environment. Other behaviors, such as pinching, were identified as a risk factor for 8.33% of perpetrators, while gossip and rumors were listed as a risk factor for less than 5% of perpetrators. By mapping these prevalence rates, the study showed that while schools often worry about cyberbullying or social exclusion, the most immediate and prevalent dangers among the student perpetrators in these specific schools were direct physical and verbal aggression.

The study also looked closely at who was most likely to be caught in the crossfire of these behaviors. Among the students surveyed, a clear pattern emerged regarding gender. The data showed a statistically significant relationship between gender and victimization, indicating that gender is a critical factor in bullying risk. Specifically, the analysis of the high-risk victim group revealed that girls comprised the majority of victims (38 out of 66 in the high-risk category), a distribution that differed significantly from the perpetrator group. Furthermore, the researchers discovered a strong link between a student's past and their current safety. Students who had previously experienced violence in their lives were much more likely to become victims of bullying again. This suggests that a history of trauma does not just affect a child's past but leaves them exposed to new risks in the school environment, creating a cycle that is difficult to break without intervention.

To address these findings, the researchers proposed a tiered set of solutions tailored to the specific risks they identified. For the extreme risk of physical hitting, they suggested immediate and structural changes, such as installing surveillance cameras in areas where teachers cannot see and implementing strict legal mediation for offenders. For the high risk of verbal threats, the focus shifts to education and counseling, requiring perpetrators to receive guidance and encouraging students to mediate conflicts among themselves before they escalate. For the lower-level risks like pinching and gossip, the strategy involves teaching students about personal boundaries and holding workshops on digital literacy and character building. This approach treats bullying not as a single problem with one solution, but as a collection of different threats, each requiring a specific type of defense.

Ultimately, this research provides a clear roadmap for schools in Indonesia and beyond. It demonstrates that by measuring the frequency and severity of different bullying behaviors among perpetrators, educators can move beyond guesswork and implement targeted strategies that address the most dangerous behaviors first. The study confirms that while bullying takes many forms, physical violence and verbal threats remain the most critical threats to student well-being in these communities. By understanding that gender and a history of violence are significant risk factors for victimization, schools can offer support to those who need it most, creating a safer environment where learning can happen without the shadow of fear.
